I regret not applying to do a Master's degree in Philosophy at Cambridge.

I take "not applying to do a Master's degree" to mean "not making any effort to do a Master's degree", right?

No, it means not applying, as it says. To be accepted onto a university course, you have to apply.

Does that mean you have to enrol, you have to register?

That comes after an application is accepted and a place is offered to the applicant.
